Deye SE-F5 (and Plus version) — is a modern lithium iron phosphate (LiFePO₄) battery with a capacity of 100 Ah and a nominal voltage of 51.2 V, providing an energy reserve of 5.12 kWh. It is designed to create reliable energy storage systems (ESS) in residential and commercial premises. Thanks to the modular architecture and flexible expansion, up to 32 such batteries can be connected in parallel to significantly increase the total capacity of the system.
The battery is ultra-efficient thanks to the use of GaN MOSFET technology, which reduces energy losses by 50% and increases resistance to high temperatures. An advanced battery management system (BMS) with an activated fuse provides comprehensive protection and reliability. In addition, the device supports convenient monitoring via WiFi, Bluetooth and the Deye proprietary application, which allows you to easily manage energy consumption both locally and remotely.

Features
The Deye SE-F5 series features optimized energy density and an integrated control unit that reduces network losses. The battery operates reliably over a wide temperature range and has effective natural cooling. Thanks to the presence of LED indicators (SOC, RUN, ALM), the user always sees the current status of the system.
A special advantage is the possibility of seamless integration with the Deye intelligent energy management system. This allows the use of smart sockets, wireless current transformers (CT) and load control to optimize costs, zero export or charge electric vehicles directly from solar energy.
Applications
- Home and commercial energy storage systems (ESS);
- Hybrid solar power plants with Deye inverters;
- Uninterruptible and backup power systems;
- Integration into the "smart home" with energy consumption control (via LoRa/WiFi ecosystem);
- Scalable energy solutions for autonomous facilities.
